The wife bought me one of the Magpul Gen 3 P-Mags for the longer M118 ammo for Christmas. My 7.62 175 gr. FGMM was scrapping the tips along the front in the standard mags so the M118 version went on my list. It is real close to scrapping but does have just a slight gap at the tip.
They measure 2.835 in. inside compared to my standard Gen 3's at 2.825 in. Now I never had any function issues with the longer rounds in the standard P-mag but the 10 rounder I use most of the time on the range is showing a pretty good groove from the bullets dragging. I do wish they would have a 10 round M118 version for use on the bench, I can tell already the 25 rounder is going to be a hassle with the need to stack the bags high. The M118 versions easily drops free from my Matrix and my Sig. I'll run some rounds after the snow blows through in a few days.
